5: called bunchers. In machines of the last mentioned kind a tobaccofiller is wound in a tobacco leaf, which is applied to an apron,restingon the rollingtable- Before being wound the edge of the leaf.(possibly part of the edge) which is 1 wound around the filler, issupplied with paste in order to. ensure the sealing of the tobacco leaf.

The, leaf may have varying shapes or sizes, de-' pending upon the shapeand size'of the finished product. As for the winding generally only one1: half of the leaf (which has been divided along its stem) is used, itis customary that either so called right hand leaves or left hand leavesare used. The leaf is usuallyapplied to the apron in such a way that theedge to be supplied with paste has anoblique position relative to thedirection of the winding, and because as per above two kinds of leaves(different halves) are used, the oblique positions of theseedges becomeopposite toeach other.:,Because the rolling table for constructivereasons should have a curved shape, the leaf edge when it is lyingobliquely will form a curved lineof rather irregular shape. The shape ofthis. curved line varies as soon as the front edge of the leaf varies toits position either by swinging (angular adjustment) or by parallelmovement.

The present invention relates to a paste supplying device developed sothat it can be adjusted conveniently tobe used for any position ordirectionpf the part of the leaf .(the'leaf edge) which is to besupplied withspaste, and further the quantity of the paste suppliedalongthe whole leaf or at parts of same can be conveniently accommodated tovarious. purposes. This latter is especially desirable, because therebythe pasting device becomes useful for any kind of bunch and if the-bunchis. to be subsequently divided. According to the invention the pastesupplying apparatus, comprising a container equipped with f valves, thecontainer being moved against a surface or the like, which opens thevalves, is mainly characterized in that the stop (shoulder) of eachvalve is adjustable relative to the stops of the other valves.

. on account of the adjustability of the'valves relative to each otherthe container may conveniently be developed slidably and rotatablyadjustable.

A preferred embodiment of the deviceaccording. to the invention is fullydescribed in the specification and illustrated in the accompanyingdrawings, said embodiment being specially adapted for a cigar-machineand the paste sup plying device being adapted to move vertically whenoperating.

Fig. 3 shows on enlarged scale the paste supplier in front elevation.

Fig. 4 shows on enlarged scale the paste supplier in plan view.

Fig. 5 shows diagrammatically in plan view the rolling table with atobacco leaf applied thereto.

.The frame I carries a rolling table 3 of known kind provided with anapron 2. The rear-part of the apron is provided with a pocket 4, towhich the filler is supplied in order to be moved later on by the roller5 in the direction of the arrow.

A paste container 6 is carried by a yoke 1, con necting two rods 8, ofwhich one is shown in Fig. l. The rods are slidably guided by ears 9 inthe frame, and one of them is provided with a collar I0 provided withshoulders and embraced by a fork on the end of an arm ll, forming partof a bell-crank lever, the second arm I2 of which is actuated by a camdisc l4 secured to a rotatable shaft 13, in such a way that verticalreciprocating movements are imparted to the rods 8 and consequently tothe container 6 when the shaft rotates. The bell-crank lever isjournalled on shaft [5 in the frame.

The container 6 comprises a front part it: and a number of rear partsl6, vertically slidable and adjustable relative to the front part andnevertheless forming a tight paste reservoir. Each of said rear. partscan be secured to the front part 'in any vertical position desired bymeans of screws I1 projecting through oblong holes l8 in said front partl5. Each rear part l6 at its bottom is provided with an outlet openingIQ for paste. Each opening is provided with a valve 20 actuated by ahelical spring 2! for shutting the valve. The cone 22 of the valves isthus by the spring forced against the valve-seat. 23 in the rear parts.

The front part I5 is rotatably journalled on a vertical shaft 24, towhich it is to be secured in any desired angular position by a screw 25.The shaft 24 in its turn is slidably journalledrin the hub 29 of an arm26 and provided with a longi h tudinal groove 21, in which enters theend of apin 28 secured to the hub. The pin prevents the shaft 24 fromrotating in the hub but not its longitudinal adjustment (changes in theheight position). The shaft 24 protrudes above the hub 29 and to its topend is secured a ring 30 provided with a pin 31. The hub 29 is providedwith a corresponding pin 32. The pins 3| and 32 are connected to eachother by means of a tightened tension spring 33. Ihe ring 30 has an ear34 provided with a stop screw 35, which by the spring 33 is forcedagainst the arm 26. The arm 26 is slidably connected with an ear 36 ofthe yoke 1 and is to be secured to said ear in any desired position bymeans of a bolt 31, extending through a longitudinal slot 38 in the earand screwed in the arm.

In operating the apparatus the container 6 by the rods 8 is moveddownwards against the rolling table 3, the bottom part 35 (shoulder) ofthe valves 20, thus forming stops, hit the front edge of the tobaccoleaf 40 applied to the apron 2. The valves yield against spring pressureand paste is delivered through the container openings 19.

If larger or smaller leaves are used, or if for some reason their frontedge is adjusted forwards or backwards, the container can be adjusted inthe corresponding direction by unscrewing the lock screw 31, which isfastened again after adjustment of the container to the positiondesired. If the adjusting movement last mentioned is considerable, itmay be desirable on account of the curved shape of the rolling table toalso adjust the position of the container vertically. This is effectedby means of actuating the adjusting screw 35.

Fig. 5 shows a right hand leaf and a left hand leaf in full linesrespectively dash and dotted lines. Their front edges 4| have differentoblique directions. When changing over from one kind of leaf to theother the screws 25 are unscrewed and the container is swung on theshaft 24 so that the valves, for instance from having had the position Aas per Fig. 5 obtain the position B. Thereby, however, the reciprocallevels of the surfaces, against which the stops 39 of the valves hit,are changed, and for this reason the vertical position of each rear part16 is adjusted after unscrewing the screws 11, so that when thecontaineris moved downwards, all stops 39 hit the leaf simultaneously,and thus all valves yield simultaneously. This adjustment of the valvesor of its stops should be made also in case the container 6 is moved byadjustment in the direction forwards or backwards.

It is obvious that the device described above and illustrated in thedrawings constitutes a special form of execution of the inventive ideaunderlying this application, and any other form of execution might havebeen chosen for the purpose. The paste container may be stationary andin such case the stop (surface) which hit the stops of the valves ismovable against the valve stops when the valves are to be opened. Thevalves may be developed in any suitable manner (as needle-valves orconical valves), and as Well their stops. The springs possibly may beeliminated if the Weight of the valves is sufficient to press them downby gravity. Even if the position of the stops according to the executionform described are adjusted by changing the position of the rear partsI6, this adjustment might be eifected in another way, for instance byshortening or lengthening the valve extensions protruding through theopening I9. Ac-

' operating direction is of no importance, however,

for the scope of the invention. It may, for instance, be horizontal.With advantage the invention may be applied to a great number of otherdevices than to cigar machines, especially if sloping or curved pastingsurfaces are to be supplied with paste, or if parts of the leafseparated from each other are to be pasted, in which case a suitablenumber. of valves is released by sufiiciently raising their stop.
